On the subject of cartoons, there was once a book that spoofed The New Yorker, including cartoons. One showed Jimi Hendrix sitting across the desk from a businessman, in what looked to be a job interview. The businessman was asking "So, are you experienced?"
Re: Homunculus/Homunculi. I am not sure this would be the proper term for a pair of angels (one fallen) on somebody's shoulders. An homonculus literally is a little man, and generally refers to a creature created out of witchcraft or magic. Then again it might be appropriate since they are sometimes represented as little forms of the protagonist on whose shoulder they sit. (i.e. a little devil Bugs Bunny and a little angel Bugs Bunny.)
The term is also used in medicine to describe the mapping of nerve endings to the brain, e.g. "the sensory homonculus."
The two angels, often featured in Warner Bros. cartoons, represent conscience and desire, or superego and id in Freudian terms.
